More than a million cases of the coronavirus have been reported worldwide and more than 53-thousand people have died from it, according to latest figures from Johns Hopkins University.
As of Thursday, the U.S. had reported more than 245-thousand cases and a death toll of some six-thousand.
Soon, the U.S. government is expected to advise people to wear cloth masks or other materials to cover the face when going outside, a shift in federal guidance amid concerns that the virus is being spread by infected people who show no symptoms.
The mayors of New York City and Los Angeles have urged residents to cover their faces already.
"We're advising New Yorkers to wear a face covering when you go outside and will be near other people. So let's be clear. This is a face covering. Again, we'll talk about the details in a moment, but it could be a scarf. It could be something you create yourself at home."
Countries with high numbers of COVID-19 fatalities, including Italy, Spain and France, are considering the use of smartphone GPS data to bolster their quarantine efforts despite their initial concerns about possible human rights abuses.
Meanwhile, researchers and drug companies around the world are completing the first stage of testing potential vaccines for COVID-19.
China Daily reports that a total of 108 volunteers have been inoculated with a vaccine prototype in the first stage of tests approved last month.
They'll be monitored for six months looking for an antibody reaction.
And the U.S. company Moderna has announced plans to start phase two of human trials of a vaccine this spring.
